Caldwell Weather and HVAC Load
Caldwell logs 5,549 heating degree days and 825 cooling degree days in a normal year, based on the closest NOAA weather station. Heating is the bigger job here. The AC still runs every summer, but it works far fewer hours than the furnace does. On average, Caldwell gets 132 freezing nights and 59 days above 90°F per year. Snowfall averages about 10 inches. On the cooling side, a 2,000 sq ft house here usually needs around 2.5 tons. A tight, well-insulated house may get by with half a ton less.

Caldwell Housing Stock
The median Caldwell home dates to 2002, according to the Census ACS. That makes the typical house about 24 years old. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Owners live in 70.7% of occupied homes, roughly 15,000 households. With a median household income of $66,663 and a median home value of $322,100, local labor rates come out near the national middle in our model.
Between 2020 and 2025, NOAA's Storm Events Database logged 2 hail days and 3 days with damaging thunderstorm winds in Canyon County. The largest hail reported was 1.5 inches across. Storms here are more likely to cause power surges than coil damage, so a surge protector on the outdoor unit is worth the small cost.
Symptoms Worth a Service Call
- The outdoor unit hums, but the fan doesn't spin
- The breaker trips when the AC kicks on
- Water pooling around the indoor unit
- Ice on the refrigerant lines or the indoor coil
- The system cycles on and off every few minutes
What Moves the Price
- The service call or diagnostic fee
- The part: a capacitor costs a fraction of a fan motor, and a compressor costs far more than both
- Whether the equipment sits in a tight attic or on a roof
- Nights, weekends and holidays
- Refrigerant type and how many pounds it takes
We lowered the national figures about 8% for Caldwell using local income, home values and the equipment size this climate needs. Real bids can still come in outside the range, so collect three written quotes.
What the Quote Should Cover

Idaho Licensing and Efficiency Rules
Idaho falls in the DOE's North region. New split central air conditioners must meet at least 13.4 SEER2, and heat pumps sold anywhere in the U.S. need 14.3 SEER2 and 7.5 HSPF2. A repair usually goes ahead without a permit, but the tech handling refrigerant must hold EPA 608 certification. Ask the company for its Idaho license or registration number before the visit.
Before You Hire
- Ask for the per-pound refrigerant price before any work starts.
- Swap the air filter and check the breaker before you call anyone.
- If the compressor is gone on an older unit, get a replacement quote before you pay for the repair.
